Read Dr. Stephen Ilardi’s The Depression Cure. He said the depressed brain is like someone getting the flu who wants to shut down. He points out that a trial of 4,000 people treated with drugs reported quietly that only 6% of the patients were better after a year of treatment with drugs like SSRIs. His treatment plan is to take 1,000 to 2,000 Omega 3 oils because they’re anti-inflammatory and anti-depression, but are not made by the body. Also, use a 10,000-lux light box a half hour a day, plus the well-known benefits of exercise, sleep, and social connection. His sixth step is to limit “rumination,” negative self-talk, by engaging in activity instead. He of course recommends seeing a trained clinician.
